You want to use descendent_path. If you have a delimiter of /, then: books/it/programming/java
would become: books books/IT books/IT/programming books/IT/programming/java Meaning you can facet on this field. If you wish to get a specific level only, then you need to either do your own splitting, or extend the PathHierarchyTokenizerFactory to be able to do it like this: 1:books 2:books/IT 3:books/IT/programming 4:books/IT/programming/java Then, you can use facet.prefix to search for a specific level in the hierarchy. Fixing the PathHierarchyTokenizer would be great for all of us.
